Mining and Processing in Westonaria

Sibanye-Stillwater’s mining and processing operations in Westonaria exemplify the company’s commitment to advanced methodologies and operational efficiency. The mining activities primarily involve deep-level underground extraction, necessitating sophisticated engineering solutions for shafts, ventilation, and ground support. Gold and PGM-bearing ore is carefully extracted using a combination of mechanized drilling, blasting, and loading. Once brought to the surface, the ore undergoes a complex processing chain tailored to the specific mineral content. This typically involves crushing and milling to liberate the valuable minerals, followed by concentration techniques such as flotation for PGMs and chemical leaching (e.g., cyanidation) for gold. The concentrated products are then further refined to meet stringent market specifications, ensuring high-purity gold and PGM outputs. Sibanye-Stillwater continually invests in optimizing these processes, enhancing recovery rates, improving safety, and minimizing environmental impact.

Advanced Underground Extraction

The extraction of gold and PGMs in Westonaria relies heavily on advanced underground mining techniques, particularly given the deep-level nature of many of the deposits. Sibanye-Stillwater employs state-of-the-art drilling and blasting technologies, along with a fleet of mechanized mining equipment, including load-haul-dump (LHD) machines and sophisticated transport systems. Safety is paramount, with continuous monitoring of ground conditions, seismic activity, and environmental factors like temperature and air quality. Advanced rock engineering and ground support systems are implemented to ensure mine stability at extreme depths. The company also invests in automation and remote operation technologies to reduce human exposure to hazardous underground environments, thereby enhancing safety and productivity in its Westonaria mines.

Concentration and Refining Techniques

Upon extraction, the ore from Westonaria undergoes specialized concentration and refining processes to yield high-purity gold and PGM products. For PGMs, froth flotation is a key technique, where specific reagents are used to selectively attach PGM particles to air bubbles, which are then collected as a concentrate. This concentrate is subsequently processed through smelting and refining to separate individual PGMs. Gold extraction typically involves cyanidation, where gold is dissolved using a cyanide solution, followed by adsorption onto activated carbon (e.g., Carbon-In-Pulp process). The gold is then stripped from the carbon, recovered through electrowinning, and finally smelted into gold doré bars. Sibanye-Stillwater employs advanced metallurgical techniques and quality control measures throughout these processes to maximize metal recovery and ensure the final products meet the exacting standards of global markets.
